Title: Manufacture of double walled steel tube
Inventor: ABE MASAFUMI
IPC: B21C1/00
Filed: 1993-03-18
Abstract: PURPOSE:To manufacture a double walled steel tube which is strong due to double walls and corrosion resisting since materials for inside and outside walls are different by concentrically superposing two steel tubes having different diameter and material by drawing and hot melting plating the superposing surface. CONSTITUTION:In manufacture of the double walled steel tube 1, the material for inside small diameter tube is stainless steel and material of outside large diameter tube is iron. The inside tube 2 is inserted in the outside tube 3, one side end part of outside tube is compressed with a space of adequate length so as the inside tube 2 is tightly wrapped. The tightly wrapping tip end part 5 is inserted in the large diameter side of a taper formed correcting hole 7 of a die 6 and projected to the opposite side. When the projecting tip end part 5 is griped and the outside tube is drawn out of the correcting hole 7, the diameter of outside tube is reduced by drawing work so as tightly superposing with the outer circumferential surface of inside tube. When steel tube 2 and 3 are heated, the metallic plating film on the surface of tube 2 is melted and the tubes 2 and 3 are integrally joined at their superposing surfaces.

Title: Video reservation delay coping system
Inventor: HIRANO TOMOHARU
IPC: H04N5/76
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a system coping with the delay and the change of a program start that is broadcasted after a program having an uncertain completion time and surely performing the recording by receiving the program delay information which is transmitted from a station via telex broadcasting, computing the start and the completion time of the program recording and starting the recording of the program when the present time reaches the recording time. SOLUTION: Data indicating a current program delay situation are transmitted from a station 101 using telex broadcasting. A video receiver 102 located in a home or the like is turned on when it becomes a program reservation time. Then, the receiver 102 obtains the data being transmitted from a broadcasting station which indicates the current program delay situation. Then, it discriminates whether a delay exists in the currently broadcasted program or not and the recording is started as planned if there is no program delay. On the other hand, if there exists a program delay, the recording start and the completion time of a reserved program are computed and the recording is stopped up to the recording start time.  Provided that, the power of the receiver is kept in a turned on condition, only the receiving of the delay information is continued so that the change in the program delay is readily coped with.

IPC: A01K89/01
Filed: 1992-03-04
Abstract: PURPOSE:To provide the spool rotation type spinning reel free from the danger of causing a trouble by the entering of a fishing line between a spool and the adjacent other member. CONSTITUTION:Projections and depressions 9d, 9e, 14c, 14d extending in the direction parallel to the axial directions of a rotor 9 and a spool 14, and the projections and the depressions are mutually engaged not to permit the rotation of the spool 14 based on the rotor 9 and to permit the movement of the spool 14 in its axial direction. A power transmission mechanism capable of rotating the rotor 9 and simultaneously reciprocatively moving the spool 14 in the axial direction when a handle 5 is rotated is disposed. Thereby, the handle 5 is rotated, the spool 14 is rotated and simultaneously reciprocatively moved in the axial direction to wind up the fishing line. Since the spool 14 and the rotor 9 are engaged with each other through the projections and the depressions, there is no danger that the fishing line enters between the spool 14 and the rotor 9.

Title: Information processor
Inventor: TAKEDA KOUJI
IPC: G06F13/40
Filed: 1984-04-25
Abstract: PURPOSE:To reduce the number of connecting ports of two or more kinds of ex- ternal peripheral devices of different data sending and receiving systems so as to ecomonize the space of an information processor, by giving two or more kinds of functions to one connecting port and switching the functions. CONSTITUTION:An information processor 10 has a connecting port 11 and the connecting port 11 becomes a connecting port for input and that for output by switching. To be concrete, when ''0'' is written on a flip-flop 110, the connecting port 100 becomes the one for output, because a tri-state buffer 140 becomes active and another tri-state buffer 150 becomes inactive. When ''1'' is written in the flip-flip 110, the connecting port 100 becomes the one for input, because the tri- state buffer 150 becomes active and the other tri-state buffer 14 becomes inactive. Therefore, the one connecting port 11 can deal with either of two kinds of external peripheral devices 20 and 30 of different data sending and receiving systems.

Abstract: PURPOSE:To improve the workability by averting the stop of the work due to the penetration disorder of a tightening jig, when an air bag is tightening- fixed between a holder and a ring retainer by a tightening jig. CONSTITUTION:A holder 1 is placed on a basic board and a rivet gun 7, and a ring retainer 3 is placed on the holder 1 through an air bag 2, and pressed manually, and a rivet 4 before caulking is inserted into each hole 1a-3a. A foot part 5 extending downward from the ring retainer 3 collides to shift a dog 13 downward, and this fact is detected by a sensor 15. After the detection, if a cylinder 18 is operated, and an arm 17 is shifted in the reverse direction, the foot part 5 is held by the stress applied outward, and the upward shift of the ring retainer 3 including the foot part 5 is regulated. Then, even if the manual pressing is released, the floating-up of the ring retainer 3 due to a variety of repulsive forces is prevented, and tightening-fixation is enabled, securing the penetration state into each hole 1a-3a of the rivet 4.
